FKIE_CVE-2024-43815

Vulnerability from fkie_nvd - Published: 2024-08-17 10:15 - Updated: 2025-02-03 15:31
Severity ?
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: crypto: mxs-dcp - Ensure payload is zero when using key slot We could leak stack memory through the payload field when running AES with a key from one of the hardware's key slots. Fix this by ensuring the payload field is set to 0 in such cases. This does not affect the common use case when the key is supplied from main memory via the descriptor payload.
